When quantifying or qualifying the printer for your critical job run Yes (perhaps) if the press is new, operated and kept up to spec, and if the printer is accurately consistently testing measuring and controlling the determined ranges ie: in Dot % on their Plates, Blankets, Inks, etc. There are...

Hello Harvey - Gordo, Terry, Stephen, Terry etc are all "spot on" in answering your important question. You may also visit this great site for more information What is GRACoL? | IDEAlliance this is a great tool that simply works as directed (certified) etc. You should then be fine.

Dear Frustrated: You have named both Flexo and Letterpress two (2) processes which may exist in one (1) common line of a printing press. The main applications described are both box print (Kraft) and "PrePrinted Liner Board" where white stocks are printed then applied later to the brown box...

The Tea Party thing may not then happened, if King George had not been so taxing. Do you recall if it was an general offset or Metal Decorator printer that bought your old Crabtree? I must say the CT-V works well in Metal Deco (flat sheet) printing thick sheets of Aluminum and or Steel, albeit...

Not mentioned in the above list of press casualties: EBCO sheetfed press made in Groton CT by the Electric Boat Company - the very same entity that builds US Submarines. I think the version I saw at a client was circa 1940's.

Actually I had customers who ran each product mentioned. One located in So CA during the 80's had on thier own purchased a full size Nebiolo web that proved to be a disaster ("never ran right") and put them oob. I recently helped a Metal Decorator update their Crab-tree Vickers by retrofitting...

This topic appears well examined if not well worn. This may be more useful if (re)created, into a new thread. This is important but may be running a bit deep with 4 or more pages. Good stuff crowding into one space often becomes unread. Greg

Appiled Densitometry Appiled Densitometry Bloodsaler all your Density guesses are just that. To know - print a Digital Print Control Wedge into your normal workflows, then fingerprint your press by individual Density values with a UGRA Plate Wedge exposed on each plate. Then you will see...

Bloodosaler You may be seeking to solve Gray Balance incorrectly from one single variable Densities yet may be ignoring the need for your Ink supplier to provide CMYK batch info or LAB values. Why? It may also help you to know the optical color (Bluish or Yellowish) cast of paper or, LAB...

Right first what type of Web press are you running and on what type of stocks? Next I agree with Chuck on a need for LAB targets and with Gordo on the need for "Hi Lo" Density references. Once found request the ink supplier to provide with each shipment batches to meet speced values (-/+ ~ DE...

Densities will vary often referred to as "Ink Take Off" which relates to ink charge laydown characteristics however in a digital press, this should not be as large as described. The issue may be related to paper stock and or ambient conditions. Your Vendor can help address, if not solve...

Closed Loop color as described in this thread is better than not. The question becomes application needs vs. costs. ROI must be present. Erik's ideas are likewise progressive for production. Why then is there resistance to this is it because the industry is conservative to change? Or does it...

Hi Gordo and you are correct. In fact after posting thought about how in FM the "irregular" shape of a FM shadow vs. the regular dot shape of AM actually creates in FM more "surface area" to gain. Conversely FM highlights feature smaller spots with a higher frequency when compared to AM...

If AM or FM press dot gain will be dot gain. Generally speaking FM prints sharper (with less ink and or gain per se) so, if printing 20 micron and you are losing Contrast (aka plugging up in the Shadows) the problem is in Plating. This is not correctly curve calibrated to compensate for the...

You are most welcome Sinyamnyam. I would make contact at the source, in this case the maker of your plates to request regular documentation of their plate calibration efforts. Not a biggie and this helps them you and the printer. I would then ask the printer (ink maker etc.) to do the same or...

Dots & Spots are not the same in or on dot gains Dots & Spots are not the same in or on dot gains Dot gain is a handy guide - a on press tool to faithfully control image reproduction. Dot Gains are derived from logarithmic Density readings meaning the less light seen = the higher density and...

Hi Light images on Flexo Hi Light images on Flexo need to be first controlled in Plating, then improved in RIP calibration then, measured on press. The data below suggests too much dot gain so suspect plating is not calibrated and you are not getting the most out of your press' ability to...

TVI Dot Gains and Print Contrast TVI Dot Gains and Print Contrast Hi Arshad on Dot Gain Balance and Contrast: Dot Gains in the Mid-tones CM&Y should generally show no more variance than ~ 3% from top to bottom except for K - which is always higher. So a CMY range +/- 3% means if you are...

Sage Advice Sage Advice Listen to Larry I know his experience is deep and advice is well founded. If you need to followup on this project: 1) First estimate your job costs and profit needs along with cash flow aspects - professionally. 2) Assuming you have a business model and plan then...
